Are you doing similar growing experiments on your tomatoes? If so,is the results similar to the pepper data?

Yes I will be doing a controlled experiment on Amish Paste tomatoes.
I have a tray of Ace 55's I'm testing out in various potting soils as they may show nute deficiencies or toxicities differently than peppers, being that they are so much faster growing they might serve as a canary for the slower growing peppers. The first 10 of those went in to "Mix C" today. I figure I numbered my trays, I'll letter my different potting soil mixes.
The tomatoes hit first true leaf and totally stalled out (but otherwise healthy), they're just sitting there not doing much of anything in the coir right now.
Something else odd.
The trays that got super-hot (114+F) early on, which didn't sprout any of the 'fast growing things' just surprised the hell out of me today.
23 days in from date of seeding, I had cayenne, garden salsa, turkish sweet ball, elephant trunk, and harbiye sprout today, along with aji dulce, bhut jolokia chocolate, bhut jolokia yellow, and 7-pot chiguanas.
23 days germination on annuum peppers? That's almost mind boggling. But it happened across three trays, so it's not just an oddball.
It's almost like the high heat didn't *kill* them, but rather, just made them all go dormant for a while. Cayenne were the dead giveaways something was weird here. In the past those have always sprouted stupid fast and grew even faster.
The only remaining peppers which haven't sprouted at this point;
Sweet French Bell
There's no rhyme or reason to it. The test trays were laid out like this (all 6 of the first test trays had the same cell arrangement)
I highlighted the cells which produced nothing in all 6 trays.
So I dunno. 0 for 6 after 23 days on 10 different varieties is just odd.
Then again it's possible it's just the crappy germination rates I've got from them getting too hot doing it to me.
After 23 days the overall germination rates on the first three trays, in order, are;
After 14 days the germination rates on the second set of test trays (coir) are
Not exactly stellar numbers there.
I'm wondering if the peat pH is off in the first 3 trays. I never did get around to checking that. Having acidic pH would explain a lot of the odd things I've seen in the first three trays of peat. Seedling cotys turning yellow. Dwarf leaves. Malformed true leaves. Poor root development. Shitty germination rates. Death of all fast growing plants (excepting four; biker billies, teken dolmasi, fresno, and turkish cayenne; those absolutely thrived)
I think I"ll pick a sacrificial cell from the remaining ones I haven't potted up, and get off my ass and do a pH test tomorrow.
I'll also do a pH test on our (rather hard) water that I've been using to water them. I always get a day or two of "few sprouts" following a watering followed by a day of "jeeezus look at all that damn data entry I gotta do" period. A theory I just formed is that my water has a high pH (it's probably above 8), which temporarily buffers out the acidic peat. It would also explain a few things with the coir, as I get no growth at all and some nute deficiency signs after I water (pH goes high, which stops a lot of nutrient uptake) then it slowly goes back to around 6.5 where the coir should be sitting naturally.
